Specification of Letters Patent.

Application filed April 10, 1918. Serial No. 227,617.

To all whom it may concern:

Be it known that I, KoNnAD WERNER LINDMAN, subject of the King of Sweden,

residing at Viistra Triidgardsgatan 4:, Stock helm, in the Kingdom of Sweden, have invented certain new and useful Improvements in Ball-Holders for Ball-Bearings and Methods for Manufacturing the Same; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention has for object a ball holder for ball bearings with one or two rows of balls. According to the present invention the ball holder consists of a cylindrical ring of sheet metal, out of which, at each one or both edges, are formed in one piece with the ring, laps or tongues, adapted to enter between adjacent balls in the ball bearing, which laps for this purpose are twisted about 90 so that they will extend from the edge or edges of the ring in axial direction with their surfaces lying in radial planes.

In order to illustrate the invention there are shown on the accompanying drawing in Figures 1 and 2 two sections at right angles to one another of a form of ball bearing provided with a ball holder manufactured in accordance with the present invention. Fig. 3 shows a part of a blank intended for the manufacture of a ball holder according to the present invention before the laps have been twisted. Fig. 4 shows the ball holder in axial direction and Fig. 5 is a side-elevation of the same.

The ball bearing consists in the well- .known manner of the inner ring a and the outer ring 6, with the balls 0 between the rings. The ball holder consists of a ring shaped part 0 provided with laps or tongues (Z which preferably are provided with openings so as to form rings into which the adjacent parts of-the adjacent halls may enter. The laps or tongues d are twisted about 90 in relation to the ring 6, so that they will extend from the edge or edges of the ring with their surfaces placed in radial direction, thus forming substantially right an,- gles to the string or ring 0.

in such a way that In the manufacture of said ball holder the strip (see Fig. 3) forming the ring 0 and the laps d is punched or pressed out of sheet metal, which strip is thereafter bent to the form of a ring, the ends of the strip being connected with each other by soldering, welding, rivets or in any other way. The laps d may be twisted as above said, either before or after the strip is formed to a ring. The ball holder may also be manufactured a tube of metal is cut in pieces of suitable length, forming rings out of which at one edge or at both edges laps d are punched or pressed out integral with the ring (as may be seen from the Figs. 4, 5), which laps are then twisted as abovestated.

The ball holder can also be manufactured for two-rowed ball bearings, in which case the'laps or rings d are formed on either side of the plate string 6, so that the latter will lie between the two series of balls.

The openings f in the laps cl are preferably foi'med in the same punching or pressing process as the laps themselves are formed.

Having thus described my invention, I declare that what I claim is l. A ball holder for ball bearings, consisting of a ring of sheet metal provided at its edge with a plurality of single laps formed integrally with the ring and twisted in such a manner that they extend from the edge of the ring in axial radial direction so that they may lie between adjacent balls of the bearing.

2. A ball holder for ball bearings, consisting of a ring of sheet metal provided at its edge with a plurality of single laps formed integrally with the ring and twisted in such a manner that they extend from the edge of the ring in axial radial direction so that they may lie between adjacent balls of the bearing, said laps being provided with holes adapted to receive adjacent parts of the balls.

In testimony whereof I aflix my signature.

KONRAD WERNER LINDMAN.
